This everyday food item is generally considered to be quite healthy nowadays, although it has sparked some controversy over the decades.
But according to a new study in The British Journal of Nutrition, consuming this food item just once a day, even every other day, will spike your risk of type-2 diabetes by 60%.
And it’s not carbs, sugars, or fat that we’re talking about.
Developing countries are often good places to study the effects of food on health.
Generally speaking, if a health condition has become a lot more common over the past three decades, and new economic prosperity brought with it an increased consumption of certain food types, the possibility of a relationship between the condition and the food is worth studying.
Chinese researchers have made full use of this opportunity since setting up the China Health and Nutrition Survey in 1991, a large database of Chinese children and adults that has been recording their health diagnoses, food consumption, exercise, and other details over recent decades.
A team of Chinese and Australian researchers picked a subset of 8,545 records of Chinese adults over the age of 18 (average age 50.9) whose information was recorded between 1991 and 2009.
At each information-recording interval, the participants reported their intake of all foods and beverages over the past three days.
Their egg consumption was taken from this record.
Diabetes was defined as based on the participants’ fasting blood sugar levels in 2009; 11.1% of the subjects suffered from diabetes in 2009.
Between 1991 and 2009, the participants’ egg consumption doubled.
The researchers first split them into four groups according to their daily egg consumption: 0-9 grams daily, 9.1-20.6 grams daily, 20.7-37.5 grams daily, and 37.6 daily grams and above.
Compared to the first group (who consumed the least), the second, third, and fourth groups had a 21%, 37%, and 25% greater risk of diabetes. Those who ate 50 grams or more had a 60% higher risk.
Those who started at low consumption and increased it during the study period had a higher diabetes risk, as did those who started with high consumption and decreased it slightly.
So how much exactly is 37 grams of egg?
The smallest eggs sold in the supermarket are, as we all know, strangely called medium-sized, and they tend to be around 44 grams.
Jumbo eggs can be as much as 63 grams.
The large ones that most of us eat are around 50 grams.
This means that we cannot eat an egg every day or every second day without increasing our diabetes risk. Just one large egg per day represents a 60% increased diabetes risk.
One egg every five days should be relatively safe, if this study is correct.
You have to remember that your egg consumption does not only include the ones that you boil or fry at home. Your egg intake also includes mayonnaise, meringues, frosting, custard, waffles, pancakes, most bakery products and desserts, battered and crumbed foods, marshmallows, some pasta, some sauces, and some soups.
